If your Schumacher Battery Charger will not turn off, it is possible that the battery has a problem and will not take a full charge. Have the battery checked.
Why Schumacher 1275A-PE Battery Charger will not turn on?
If your Schumacher Battery Charger will not turn on even when properly connected to power, the battery may not need charging because it was recently used in a vehicle and is fully charged. If the battery is in a vehicle, turning on the headlights will lower the battery voltage in a few seconds, and the charger should then turn on.
What to do if the Schumacher Battery Charger needle moves to the right and clicks?
If the meter needle on your Schumacher Battery Charger moves to the extreme right, stays briefly, returns to zero, and you hear clicking, it could mean the battery is severely discharged but otherwise good, or the battery is defective and won't accept a charge, or the charger is cycling after a circuit breaking overload. Allow charging to continue until the battery recovers enough to take a charge. The circuit breaker will continue to cycle, and the needle will swing side to side until the battery has recovered. Also, have the battery checked and wait for the charger to automatically reset itself.
Why is the charging current low on my Schumacher Battery Charger?
If the charging current on your Schumacher Battery Charger is less than its full output rating, it could be because the battery is partially charged, defective (with crusted plates), or the AC power supply is low. Continue charging. Have the battery checked and replaced if needed. Try plugging the charger into another grounded AC outlet.
How to troubleshoot a Schumacher 1275A-PE with no meter reading?
If there is no meter reading on your Schumacher Battery Charger, it could be due to reversed connections, a poor electrical connection, a dead AC outlet, or a defective battery. Ensure the charger is plugged in. With the charger unplugged, reverse the clips and reconnect them, rocking them back and forth to ensure a good connection. Clean the clips and battery poles before reconnecting. Test the AC outlet with another appliance. Have the battery checked.
Why does the Schumacher Battery Charger needle pulse after several hours?
If the meter needle pulses or fluctuates every few seconds after three hours without slowing down on your Schumacher Battery Charger, it could be because two or more batteries are connected in parallel, the battery is 200 ampere-hours or larger, or the battery is connected to an application that draws a small current. Avoid parallel charging. If the battery requires more time to charge, continue charging.
